IMPROVEMENT IN HOSE-COUPIY|INGS.

The Schedule referred to in these Letters Patent and makngipart of the same To all whom. it may concern:

Be it known that I, CHARLES POWELL, of Birmingham, England, 4and Kingdom of Great Britain, have invented anew and improved Hose-Coupling; and I do hereby declare that the following is a tnll, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference bein g had to the accompanying drawings forming part of this specification.

This invention lrelates to improvements in couplingjoints for hose or other pipe; and consists in providing longitudinal brackets or projections on the end of' one section with notches fronting the center, and a rotating collar on the other section behind `the flange, and spiral flanges for wedging in thesaid notches when the joints are placed together and the said collar is turned on its-section, clamping the flange between it and the flange or end of the othersection firmly together. Y A

The flange of the section on which the collar turns has radial notches engaging the projections of the other section, to prevent it tiom being turned with the revolving edging-collar by the frictional contact.

The revolving wedging-collar may have lngs for the 'attachment of a spanner for turningit, or a lever may bepermanently attached to it. Figure 1 is a longitudinal sectional elevation of my improved coupling-joint. Figure 2 is a side eleva-tion of the same.

Figure 3 is an end elevation of the section with the clamping-ring. v y Figure 4 is anend view of the clamping-collar, with a lever attached to it. f

A represents the section with the longitudinal projections B at the en'd, preferably two in number, and arranged opposite each other across the axis.

These projections have notches in the sides fronting the axial line, which receive the spiral flanges D of a collar, E, placed onv the section F behind the flange G at the end, as many spiral flanges D being placed on the coll-ar- E as there are' projections B on the section A.

The flange G 0f the section F has notched projections, H, in which the projections B'engage where the ends of the two sections are placed together, so as to prevent the section F froin turning with the collar E by the frictional contact thereof'.

The collar E is provided with lugs, I, for the attachment of a Spanner for turning it, or itmay have a hand-lever, K, permanently attached to it.

A packing-gasket, of any suitable substance, may he placed betweenthe ends of the sections before they are clamped together.

Having thus described my invention, c I claim as new and desire to secure by Letters latent- The section A, providedwith notched projections B, and the section F, provided with the collar E, with spiral flanges D, all combined and arranged substantiallyas specified.

CHARLES POWELL.
